The purpose of the ACL Audio Interface module is to interconnect modular
synthesizer systems with both professional studio and stage equipment.
It allows external stereo audio signals to be routed in and out of the
modular system, using consumer level 1/4" jack line inputs and outputs,
whilst - thanks to comprehensive headphone monitoring - also serving as
an effective live mixer for combining audio from an external setup with
audio from your modular system.
The combination of a studio quality signal path, flexible routing
possibilities, and a headphone amplifier - capable of driving both high
and low impedance headphones, with low distortion - makes the connection
between these different environments effortless and sonically
transparent.
To ensure the highest possible signal quality and flexibility, the ACL
Audio Interface offers balanced-to-unbalanced and unbalanced-to-balanced
stereo lines throughout, with level controls. Additionally, the stereo
signal from the auxiliary input features its own level and mute
controls, and thus can be mixed together with the signals of both stereo
lines (using AUX you could connect devices such as an external DJ
mixer, laptop, or even a phone), allowing even more live performance
possibilities.
The headphone amplifier can also get its signal from both lines, after
the level control and mixing stage, or can be muted, effectively turning
the interface into a functional live mixer (for when a larger mixer is
not wanted or needed), further enhancing the Audio Interface's live
credentials.
Moreover, since the headphone amplifier is only AC-coupled at the input,
not at the output, there is on-board DC protection circuit included.
This results in truer bass response in the headphones, and also offers
the maximum possible protection against damage to your headphones.
Unlike many such headphone amplifiers on the market, our module also has
a 'soft start' function, preventing painful and damaging (to both
headphones and ears!) clicks in the headphones when powering on the
system. There is also an overload indicator for both lines.
Whether you want a peerless signal path from your studio to your modular
system (and back), or to take your system on stage and combine it with
other equipment - with or without an additional mixer - we believe our
Audio Interface is an outstanding choice.
